Colorado Sports Betting: Best CO Online Sportsbook Sites May 2025

Colorado betting promos and bonuses

With 15 legal sports betting sites, Colorado is one of the most competitive states in the US, which has also led to some of the best sportsbook promos and loyalty programs in the country.

While several sportsbooks do offer deposit match bonuses, the most common Colorado sportsbook promo is first bet insurance in some form or another. Remember, if your bonus is insurance on your first wager, you won’t see any bonus monies if your first bet wins, only if it loses.

Now, if you’re a veteran sports bettor already signed up at one or more of Colorado’s 15 online sportsbooks, the welcome bonus may not be available, but that doesn’t mean you can’t continue to shop around.

Bettors are allowed to redeem one welcome bonus at each online sportsbook, and when more launch in the future, cagey veteran sharks can redeem those, too. Otherwise, keep close tabs on ongoing promotions once you log into your accounts. Odds boosts, reduced juice, bonus bets, and other reward programs encourage you to stick with one sportsbook over another.

Top Colorado betting sites

With 15 available, all Colorado betting sites have something to offer the casual sports bettor. However, in such a crowded space, operators continue creating unique experiences for players to keep them returning. The advancements in live video streaming technologies allow several sports betting apps to offer live video streams of their betting events.

In contrast, most offers live in-game betting where you can wager on the next play, quarter, or team to score. This constant desire to up the ante and invent creative ways to improve the user experience always benefits you, the player.

Here is what the sportsbooks in Colorado are boasting these days:

Why FanDuel is the best sportsbook in Colorado 🔵

FanDuel was one of the first online sportsbooks to launch in Colorado in 2020. All these years later, this industry leader remains the top sportsbook in the Rocky Mountain state. Numbers don’t lie, and if you check out FanDuel’s app store rating on iOS and Android for betting apps, it’s even ahead of rival DraftKings for producing quality products and user experiences.

To claim the welcome offer, new FanDuel users will need to register for an account, make a first-time deposit of $5 or more, and place an initial wager of at least $5 to get $200 in bonus bets — no FanDuel promo code necessary.

Additionally, once the sign-up offer expires, FanDuel is well known for offering best-in-class weekly promotions and perks like boosted odds, same-game parlays, and rewards programs that provide benefits to loyal bettors. In fact, both new and existing users will receive a boost or bonus each day this summer.

Though others have jumped on the trend, FanDuel was one of the first-to-market operators of live video streaming. Bettors can watch live events in the app while keeping an eye on their bet slip simultaneously on one of the best live betting sites. With dozens of betting markets to choose from, like the NFL, European soccer, and PGA tour events, FanDuel has something to offer every bettor.

Bettors should also applaud FanDuel for their superior security measures and easy-to-access customer service team. At some point, a question will arise, and if you want answers quickly, you’ll want to reach out to FanDuel’s all-star customer service team.

Colorado sportsbooks honorable mentions

Although the remaining operators didn’t crack out the top five Colorado sportsbooks, we encourage you to check out the SBR review at least and dig into whether or not their services are what you are looking for in a sports betting site and app. Some of these sportsbooks have friendly signup offers, such as the BetRivers bonus code or the Bally Bet promo code.

CO sports betting key developments and updates

Colorado sports betting summary

How we rate and review Colorado sportsbooks

Sportsbook Review’s editorial team independently reviews each Colorado sportsbook for quality. SBR’s team of experts comes from various sports betting backgrounds, allowing for a more comprehensive critique of operator’s sites and sports betting apps. Since there are 15 online sportsbooks to choose from in the Rocky Mountain State, the margin for error/originality between sportsbooks is quite slim. However, SBR’s editorial team does focus most of its time and attention on the following six categories.

Welcome bonuses and promotions

Operators know they only get one chance to make a first impression. So, they need to emit the proverbial bat signal and draw attention to their products via substantial welcome bonuses and ongoing promotions to entice players to return to their platform. These days, the most common welcome bonuses are deposit matches, bonus bets, and first bet insurance, which allows first-time players to be slightly more aggressive on their first wager.

Once the sign-up offers expire, account promotions and perks include reduced juice, boosted odds, bonus bets, first bet insurance, and loyalty reward programs. These allow players to accumulate points on every bet that can be redeemed for future bets, tournament entries, and other VIP experiences not found anywhere else.

User experience

Grading a user experience is challenging because to each their own, right? However, we can all agree that we know the difference between a positive user experience and a negative one. The app should be solid, not “hang” or “lock up” or randomly stop working. The site should be easy to navigate from page to page. Creating a bet slip should be easy to use. Banking options should be easily accessible.

As more states and operators have launched in the United States, we have learned that the more seamless the process, the better the user experience. Fewer clicks to get to where you want to go, the better.

Sports bet variety

We all know that the four major sports in the United States are NFL, NBA, MLB, and NHL, but sports bet variety on these platforms matters. Thus, we are rating sportsbooks based on access to European soccer markets, PGA majors, tennis majors, UFC events, and heavyweight boxing bouts because a Paul brother will probably fight every six months now.

Individual sports aside, the types of bets matter, too. Moneylines, point spread, and point totals betting are great for novice players, but we’ll also want to see operators offering live in-game betting, player props, parlays, teasers, and futures odds on the board.

Banking options

Before legal sports betting in Colorado, the most significant friction point to entry was safe and secure banking options. This is no longer an issue as most online sportsbooks in the Rocky Mountain State accept major credit and debit cards, Paypal, bank wire transfers, and other e-wallet options.

Payout speed

SBR’s editorial team reviews the withdrawal request process for each of Colorado’s online sportsbooks. The average time to receive a payout is five business days, but it can be longer if you request a physical check be mailed to your residence. In that case, it can take up to 15 business days. The faster the payout speed of an operator, the higher the rating SBR awards the site.

Security and customer support

With personal and financial information being beamed back and forth between online sportsbook operators and bettors, Colorado sportsbooks must use the latest encryption software and prioritize data security. You don’t want bad actors accessing personal data because an online sportsbook was lazy in setting up firewall protections for your accounts.

If you ever run into an issue, Colorado sportsbooks must make customer service reps easy to access at all hours of the day. Most sites and the app now offer a live chat function that can help get you answers to all your queries as soon as possible rather than waiting on hold via phone or waiting on an emailed response back. The CS team, via live chat, answers your questions on demand.

How to start betting in Colorado

Suppose you’re eager to back the Denver Nuggets heading into the NBA playoffs or champing at the bit to wager on the Denver Broncos to flip the script with Sean Payton coaching Russell Wilson. In that case, there are a few things to do before placing your first bet at a Colorado online sportsbook or sports betting app. Here is a quick and easy explainer of how to get started betting in the Rocky Mountain State.

Select a sportsbook licensed in Colorado

First, do your due diligence by reviewing some or all of the online sportsbooks SBR’s editorial team rated. This will help you make an educated decision before investing time and making a first deposit with a Colorado sportsbook operator.

When you’ve found a favorite, it’s time to either sign up via their online sportsbook on a desktop/laptop computer or download their app onto a smartphone or tablet.

Register online

The registration process is clean and straightforward and should take less than five minutes.

Fire up your sports betting app to start. The operator will require you to provide basic personal information like your full name, home address, email address, phone number, date of birth, and social security number. Sportsbooks need your social security number for various reasons, namely for age verification and to avoid duplicate accounts that hackers can make in your name.

The operator will also likely send you an email to activate your account. Once you click that link, the sportsbook will ask you to create a unique username and secret password. The strongest account passwords combine uppercase and lowercase letters, numbers, and special characters.

Deposit and claim a bonus

After registering and logging in, head over to the cashier’s page. Here you’ll sync your preferred banking method with your Colorado sportsbook account. The most common deposit options are credit card, debit card, bank wire transfer, or third-party services like Paypal.

At this step, before you submit the amount you want to deposit, you’ll want to have any required welcome bonus promo codes handy to punch into the specified field on the screen. The last thing you want to have to happen is to make a first deposit and leave cash on the table because you forgot a promo code.

Select and finalize your bet

Now that you’re registered and have made a first-time deposit, it’s time to review the betting markets available. A positive user experience allows you to seamlessly move around the sportsbook from one sport and event to another with lag times. Building a bet slip with a combination of different wagers on the same ticket should be easy.

Once your bet slip is complete, finalize your bet by clicking submit. You’ll receive a bet confirmation once it goes through.

Win and withdraw your payout

Congrats, your first bets were winners! Maybe you’re eager to get some return on investment sooner rather than later. You can quickly request a withdrawal by returning to the cashier’s page. Payout options are via bank wire transfer, third parties like Paypal, or you can even request a withdrawal via check by courier. Just know that it can take up to 15 business days to receive your funds if you order a physical cheque.

Colorado sports betting handle

Thanks mainly to the NFL regular season, legal Colorado sportsbooks — both mobile and retail — raked in $518 million or more in the last three months of 2022. The state’s total betting handle for 2022 was $5.17 billion, up from $3.83 billion in 2021.

Of those total bets, Colorado enjoyed tax revenues of $19.7 million in 2022, up from $11.7 million the previous year. In 2024, sports betting generated more than $30 million for the Rocky Mountain State and the sports betting handle eclipsed $6 billion for the first time — impressive figures for a state with 5.8 million people.

Colorado sports leagues and teams to bet on

You can bet on Colorado’s professional teams, like the Broncos, Nuggets, Rockies, and the Stanley Cup Champion Avalanche, with the most popular betting markets like moneylines, point spreads, and point totals. You can also wager on in-state college teams, which is fun during bowl season and March Madness basketball tournaments.

While backing your hometown teams can be fun, it’s often not the smartest betting strategy. Bet with your brain, and don’t let emotion get in the way of handicapping a matchup. Keep an eye on injury updates, suspensions, and depth chart changes that may be hidden in headline news.

Denver Broncos 🏈

The Denver Broncos are the most popular sports team in Colorado, which is hardly surprising given the NFL's dominance of the sports landscape in America. The Broncos have an impressive eight AFC championships, many of them owing to the spectacular play of Hall of Fame quarterback John Elway. After winning back-to-back Super Bowls in 1997 and 1998, Elway retired on top.

The Broncos carried on, of course. They won another Super Bowl in 2015, this time the result of an incredible defense. The team was sold to new ownership in 2022 for $4.65 billion, who quickly brought in Sean Payton as the new head coach in an attempt to return to title contention.

Denver Nuggets 🏀

For most of their existence, the Denver Nuggets were afterthoughts of the NBA's Western Conference. While teams like the Lakers and Spurs were winning titles, the Nuggets just hung out in the background. Sure, they would win the odd Northwest Division title, but those mean very little in the NBA compared to championship rings.

That all changed when they drafted Nikola Jokic in 2014, with the 41st overall pick. Within a few years they were regular playoff contenders. In 2023, led by Jokic's phenomenal all-around play, the Nuggets won their first NBA championship. 

Colorado Rockies ⚾

The Colorado Rockies joined MLB as an expansion side in 1993. Despite the thin mountain air seeing baseballs fly out of Coors Field at an above-average rate, the Rockies haven't seen much success. They boast just a single NL Pennant from 2007 but were swept in the World Series by the Boston Red Sox.

Colorado sports fans still love the Rockies, even without any consistent success. After all, it's one of the only options for pro sports all summer, along with the Colorado Rapids of the MLS. The Rockies remains a popular betting market on many Colorado sportsbooks, thanks in part to MLB's daily schedule of games.

Colorado Avalanche 🏒

The pain of hockey fans in Quebec City became the joy of puckheads in Colorado when the Nordiques packed their bags and moved out of Canada and into the Mile High City in 1995. The team owes most of their historic success to the move, winning 12 Division titles, three Presidents' Trophies, and a trio of Stanley Cup championships in Colorado.

The Avalanche continue to entertain CO sports fans with winning seasons, thanks in part to drafting sniper Nathan MacKinnon with the No. 1 overall draft pick in 2013. 

Other CO sports betting ⚽

Online sportsbooks also offer betting odds for Major League Soccer (MLS). So, if you’re interested in backing the Colorado Rapids, you’re in luck. Other less popular betting markets include international soccer, PGA tournaments, men’s and women’s tennis majors, and UFC/MMA fight cards.

Legal sports betting and regulations in Colorado

There are currently 15 online sportsbooks and sports betting apps to choose from in Colorado. There could have been more, but TwinSpires shuttered mobile operations in May 2022, BetWildwood shut down the following month, and WynnBet closed in August 2023. SI Sportsbook, Betway, SuperBook, and Betsafe also closed their sportsbooks in mid-2024. There are 33 total licenses available. So, there remains room for growth in the Rocky Mountain State.

Colorado’s online and mobile sportsbooks

Land-based Colorado sportsbooks

There are 12 land-based, retail Colorado sportsbooks. However, they are far from major city centers like Denver, and most listed below are in Black Hawk, Colorado.

Who can bet on sports in Colorado?

Legal age 🎂

You must be at least 21 to wager on sports in Colorado.

Mobile betting 📱

Mobile sports betting went live in Colorado in May 2020 and remains a hot commodity, with 15 operators offering sports betting app services.

Remote registration 💻

You do not need to visit retail sportsbooks to register for an online sportsbook account, and you can take care of sign-up via computer or sports betting app. This process takes less than five minutes to complete.

Within state borders 🌎

You don’t have to be a full-time resident of Colorado to wager via online sportsbooks or sports betting apps, but you need to be physically within state borders. Sports betting operators use geotagging software to determine each person’s location when they log into or place a bet using Colorado online sportsbooks.

Retail sportsbooks 🏢

In addition to the 15 online sportsbooks and sports betting apps, Colorado offers 12 retail sportsbooks where bettors can wager in person. Most are located in Black Hawk casinos.

Taxable winnings 💸

Uncle Sam and the state of Colorado want a slice of your sports betting profits. You’ll be taxed at the federal and state level on profits only. The feds take about 24%, while Rocky Mountain State snatches 4.63%. Remember, you can offset tax liability when you deduct losses from your profits.

What you can't bet on in Colorado

As we’ve touched on throughout this sports betting guide, Colorado is a hotbed for NFL, MLB, NHL, and NBA wagers, but there are some categories you still can’t wager on or that the Department of Gaming is keeping on the sidelines for the near future.

Politics ❌

You can’t wager on politics in Colorado. So, your hopes of laying down some scratch on the odds to win the 2024 US presidential election will have to wait.

Entertainment award ceremonies ❌

Entertainment award shows like the Oscars, Emmys, and Grammys are not allowed in Colorado, and you will not find odds at online sportsbooks. However, unique annual events like the NFL Draft are legal to wager on yearly.

eSports ✅

eSports betting in Colorado is an interesting case study in the gaming industry. You may bet on eSports in Colorado, but each event must be approved individually, and there is no blanket approval process. So, the video game tournaments listed in various sportsbooks may vary depending on if the eSports Integrity Commission approves the event.

What about Colorado college sports? 🎓

Several state laws restrict wagers on in-state collegiate teams, but you can bet on all college sports in Colorado, both in-state and out-of-state programs. This means sportsbooks will feature odds on Deion Sanders’ Colorado Buffaloes winning the Pac-12 this fall. However, you won’t find any college player prop odds on the board because they are prohibited.

Responsible sports betting in Colorado

With 15 online and 12 retail sportsbooks active, Colorado’s Division of Gaming (CDOG) is the governing body overseeing sports betting. The CDOG’s mission is to ensure honesty and integrity in the state’s gaming industry. They are in charge of reviewing applications, issuing licenses, managing revenues, enforcing laws, and issuing fines when operators color outside the lines.

The CDOG audit department conducts regular compliance reviews to ensure operators keep honest and accurate accounting books and pay their taxes promptly. The Technical Systems Group of the CDOG verifies safety and security protocols of mobile sports betting products, including field tests to ensure geofencing and identity verification measures are working in the remote registration world.

The CDOG charges a $10,000 application fee to interested operators and, if approved, charges a $125,000 licensing fee that’s good for two years.

A portion of tax revenue from sports betting goes towards treating problem gambling, including the state’s 24-hour hotline: 1-800-522-4700.

National U.S. gambling helpline: 1-800-GAMBLER

Sportsbooks to avoid in Colorado

Once upon a time, before Colorado offered interested parties dozens of online sportsbooks, sports betting apps, and 12 retail sportsbooks, bettors would often seek the services of offshore sportsbook operators. These blacklisted sites are unregulated by governing bodies at the federal and state levels. So, you’ll want to avoid these sites and stick to the ones SBR’s editorial team has reviewed.

Below are three examples of offshore sportsbooks that engaged in nefarious business practices rather than providing Colorado sports bettors a positive user experience.

Growth of sports betting 📈

When the U.S. Supreme Court repealed PASPA in 2018, the growth of legal sports betting in the United States skyrocketed. Close to three dozen states have since legalized some form of sports betting, with the most common legislation including the licensing of online sportsbooks and mobile betting apps. Check our legal sports betting tracker to find out more about any state you're interested in. 

Over the past few years, large states like Ohio and Massachusetts have enjoyed massively successful online betting launches. Sports fans get an extra way to engage with their favorite teams, and the states earn plenty of much-needed revenue from licensing fees and taxes.

Last year, legal North Carolina sports betting arrived on March 11, 2024, bringing eight of the best sportsbooks in the country to the Tar Heel state.

However, all eyes will be on Missouri in 2025, with legal sports betting set to launch in the Show-Me State sometime in mid-to-late summer. Stay up-to-date on the latest news and updates as they're announced by following our Missouri sportsbook promos page.

The states closest to offering legalized sports betting next are Oklahoma and Hawaii, but we don't expect either until the first half of 2026 (at the earliest).
